Reasons for Olive Tree Flower Drop

With the right olive tree care and pruning, you can have beautiful petite olive tree flowers and a heavy olive harvest afterward. However, environmental consistency is essential to flower and fruit sets of olive trees. Any sudden change can cause olive fruit or flower drop on olive trees.

Environmental Changes

Olive trees are sensitive to changes in their environment. Sudden fluctuations in temperature or climate can lead to olive tree flowers falling off.

Olive trees grow best in a sunny, permanent site where they can actively grow year-round. They require full sun for healthy flowers and fruit production and may drop flowers if they are placed in too much shade.

Frost

Olive tree flowers are not tolerant to frost. Unseasonably cold spring weather in areas that normally stay warm may cause olive tree flowers to drop on outdoor trees. Frost nipped olive tree flowers and buds will turn brown and mushy, then drop from the tree.

Transition Shock

In cooler climates, olive trees are often grown in containers and moved inside or out depending upon the weather. These potted olive trees can be even more prone to olive tree flower drop or leaf drop because of the frequent environmental changes they experience as they are moved in and out.

Cool Drafts and Watering Issues

Olive tree flowers falling off a potted olive tree may also be caused by cool drafts, as well as under or overwatering. An olive tree dropping flowers may be a sign of drought or other changes in watering.

When water is scarce, an olive tree will drop flowers or fruit to conserve energy. Flooding, waterlogged soil, or over-watering can also cause olive flower drop. Olives grow best in well-draining soil with regular irrigation, especially in times of intense heat and/or drought.

Nutrients Deficiency

Olive trees are generally acclaimed for their ability to grow in poor, under-fertile soils. However, olive tree flowers falling off an olive tree can be a sign of a potassium deficiency.

Potassium is vital for flower and fruit set, and the overall health and vigor for most of the trees. If you wish for healthy, high yields from your olive trees, begin a fertilizing regiment in early spring with a fertilizer high in potassium or designed specifically for olive trees.
